Gerdeka Hartlevsdotter, or Hartlefsdotter, also called Gerdica (1370-1438), was a Swedish Bridgettine nun. She was the abbess of Vadstena Abbey from 1403 until 1422. Gerdeka Hartlevsdotter was the daughter of Hartlev Bolk (d.1390) and Ingeborg (d. 1400) from Skänninge. Her mother became a member of the Vadstena Abey as a widow, and Gerdeka had her father reburied in the abbey cenetary as an abbess, when it became allowed for non-members of the order to be buried at the abbey during her tenure as abbess. Gerdeka was elected abbess in 1403, after the deposition of her predecessor Ingegerd Knutsdotter. Her reign has been described as a golden age for the abbey.
